More than one match found for domains regex

[ItayBenAvi]

Describe the bug
mail-parser fails to run regex on domains that ends with ".id"
My scraper fails on them specifically

To Reproduce
Change domain to end with .id

Change in const.py:51 the regex to negative lookbehind with whitespace and dot:
(
r"[^\w](?:id\s+(?P.+?)(?:\s*[(]?envelope-from|\s*"
r"[(]?envelope-sender|\s+from|\s+by|\s+with"
r"(?! cipher)|\s+for|\s+via|;))"
)
(
r"(?<![^\w\.])(?:id\s+(?P.+?)(?:\s*[(]?envelope-from|\s*"
r"[(]?envelope-sender|\s+from|\s+by|\s+with"
r"(?! cipher)|\s+for|\s+via|;))"
)

Expected behavior
ID extracted correctly and only once

Environment:

• OS: Linux
• Docker: yes
• mail-parser version 4.1.2

We've got the same issue/behavior (also on v4.1.2).

The parsing is erroring if any of the mail "received" contains a domain in .id

Here is a simple reproducible example:

The email containing a domain with .id

Received: from web.myhost.id
	by smtp.domain.com (Proxmox) with ESMTPS id SOMEIDHERE
	for <email@example.com>; Wed, 19 Feb 2025 15:00:00 +0700 (WIB)
From: "Someone" <someone@web.myhost.id>
To: <email@example.com>
Subject: OK
Message-ID: <0000000-0000-0000-0000-000000000000@web.myhost.id>
Date: Wed, 19 Feb 2025 12:00:53 +0000

The code

import pathlib
from mailparser import parse_from_string

with pathlib.Path('/path/to/file/test.txt').open() as file:
    parse_from_string(file.read()) # Gives an error log

# More than one match found for [^\w](?:id\s+(?P<id>.+?)(?:\s*[(]?envelope-from|\s*[(]?envelope-sender|\s+from|\s+by|\s+with(?! cipher)|\s+for|\s+via|;)) in from web.myhost.id by smtp.domain.com Proxmox with ESMTPS id SOMEIDHERE for <email@example.com>; Wed, 19 Feb 2025 15:00:00 +0700 WIB
# More than one match found for [^\w](?:id\s+(?P<id>.+?)(?:\s*[(]?envelope-from|\s*[(]?envelope-sender|\s+from|\s+by|\s+with(?! cipher)|\s+for|\s+via|;)) in from web.myhost.id by smtp.domain.com Proxmox with ESMTPS id SOMEIDHERE for <email@example.com>; Wed, 19 Feb 2025 15:00:00 +0700 WIB

Replacing the domain by a different tld than .id removes the error.
